The Ultramasx UltraFiltersTM are composed of 4 layers: sterilising paper, ultra-fine activated carbon, a special HEPA (High-Efficiency Particulate Air) grade 12 layer able to capture more than 99.97% of particulate matter of a mere 0.3 micrometers or PM 0.3 and finally a special waterproof non-woven fabric.

How do I change the filters?

In order to replace the Ultramasx UltraFiltersTM cartridges, first pull both sides of the front panel and remove it. Once the filtering cartridge (green front) is visible pull up both sides of it and remove it. Please inspect the reverse side (white side) of the filtering cartridge: we recommend changing the filter when the area of smudge created by the captured particulate on the reverse side of the filter becomes too wide and dark. Please refer to our video tutorials page.

Yes, every Ultramasx UltraOne™ box includes two exhaust filters. The exhaust filter has to be positioned on the exhaust valves covering them from the inside of the mask.The exhaust filters are washable and reusable. It is recommended to clean them on a daily basis. 

How and when do I charge the Ultramasx UltraOne™?

A LED light on the side of the mask indicates the battery level. When the light is flashing red during the use of the mask it indicates that the battery is running low and needs to be re-charged. Plug in the cable to the USB port for charging. A red light indicates the charge is running. When the green light appears the mask is fully charged.

How are the straps adjusted?

The straps of Ultramasx UltraOne™ can be used in two main positions: either behind the ears or behind the head. Positioning the straps behind the ears is a wider setup and can be tightened as needed with the clips provided in the box. The behind the head setup is tighter and provides maximum security.

Behind the ears: Connect one silicon strap to the pins on one side of the mask, the top one and the bottom one. Do the same for the other strap on the opposite side. Then wear the mask pulling the straps to the back of the ears. If this setup is too wide, connect the straps with the clips provided behind the head to tighten it as needed. 

Behind the head: Connect one silicon strap to the pins at the top of the mask first. Then connect the second strap to the two pins at the bottom of the mask. Then wear the mask pulling the straps behind the head.

Please refer to our video tutorials page.

Cleaning of the silicon face seal: the face seal can be directly dismantled from the reverse side of the mask and can be washed with water or ethyl alcohol or put into boiling water for germicidal treatment.
